Local Environmental Conditions
Carmel Catholic HS's Football Field is set in the Mundelein suburban landscape of Lake County, Illinois, with oak, maple, and birch as the main surrounding tree pollen sources. Surrounding Lake County woodland and farmland contribute substantial grass and tree pollen, while the flat Midwest landscape allows pollen to disperse widely and mugwort extends exposure into September throughout this Lake County northern Illinois suburban Catholic school.
Situated a football venue in Mundelein, Carmel Catholic HS's Football Field shares the area's pollen timeline, beginning with maple and elm in March before oak extends the tree season through April. Grass pollen builds through May and June, and ragweed pollen builds steadily from August into September. A humid continental climate drives a sharp spring tree peak and an equally distinct late-summer ragweed run throughout the year.

Does pollen in Mundelein come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Mundelein based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Mundelein, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
